There was a zope-2.5.x originally. 2.6.x is backwards compatible
so that it was OK to just replace the 2.5 pkg with it.
I admit that this looks strange, but renaming the directory,
thus breaking updates, PKGREVISION bumps and fixing dependencies
just for cosmetic reasons isn't nice either.
(2.5 was very different from 2.2, so just a "zope2" directory
name didn't make sense.)

Actually, 2.2 can be removed. It is completely outdated.

Imo, for pkgs where it is appropriate to keep multiple
versions in parallel the directory names should enough
of the major number(s) to identify that branch. And such a
branch should stay within that directory for its lifetime;
this xxx->xxx.old & xxx.new->xxx renaming sucks.
(Of course, one doesn't always know when a pkg is initially
imported...)
